Outline of Final Research Achievements

This research will create essential calibration standards for SIMS analyses of H2O and CO2 in rhyolite. Standards will include natural and synthetic glasses, selected following FTIR analysis of their volatile distributions. These standards will enable current and future studies of volatiles in rhyolite glasses, and data obtained during their characterization will also yield insights into degassing and hydration processes.
